FEA and Experimental Analysis of Crane Hook Considering Different Cross sections and Materials

Abstract

Crane hook is significant component used for lifting the load with the help of chain or wire ropes. Crane hooks are highly liable components and are always subjected to bending stresses which leads to the failure of crane hook. Failure of a crane hook mainly depends on three major factors i.e., dimension, material, overload. To minimize the failure of crane hook, the stress occurred in it must be studied. Structural failure of the crane hook may happen as a crane hook is subjected to continuous loading and unloading. In this paper the design of the hook is done by analytical method for the different materials like aluminium, cast iron, high strength low alloy steel and Structural Steel. CATIA software is used for modelling the crane hook and ANSYS software used to find out the stresses induced in it. This result helps us for determining of stress in existing model. By predicting the stress concentration area, the hook working life increase and reduce the failure stress.
